All day I get returned to orbit if I try and join a fire team. WTF? I used to get StrictNAT warnings but now I switched to a business modem and I don't get those. I just get returned to orbit if I am engaged in cooperative play for more than 15 seconds. I am pretty sick of this now and close to giving up on this game if I can't play multiplayer or cooperative play in a fireteam. Strikes work just fine. Crucible works just fine. Just not fireteams in any of the game modes. Any solutions? Am I unique in this?
